AirCraft Elbow With O-ring 4mm 1/8' M PU Hose Fitting
At a Glance: 90° push-in elbow with O-ring seal: 4mm tube x 1/8' Male BSP for neat, leak-resistant routing.
The AirCraft Elbow W_o ring 4mm 1/8' M PU Hose Fitting is a compact 90° push-to-connect elbow designed for clean pneumatic routing where space is limited and sealing matters. It connects 4mm tubing to a 1/8' male BSP threaded port, and includes an O-ring seal to help improve leak resistance at the threaded connection. Ideal for regulators, manifolds, valves, air control blocks, and compact compressed-air installations, this elbow helps prevent kinks, reduces hose strain, and keeps your air line layout looking professional.
Get the tight-space benefits of a 90° elbow plus the extra sealing help of an O-ring—perfect for clean, dependable pneumatic builds.
Features
- Integrated O-ring seal Helps improve sealing at the threaded connection for leak-resistant installs.
- 90° elbow profile Makes tight turns simple and keeps hose routing neat.
- 4mm push-in tube connection Quick installation with push-to-connect convenience.
- 1/8' Male BSP thread Fits common pneumatic ports on regulators, manifolds, valves and fittings.
- Fast serviceability Release collar allows quick tube removal when the system is depressurised.
Benefits
- Better sealing confidence: The O-ring assists with leak resistance on the threaded joint.
- Cleaner hose routing: Reduces kinks and clutter in compact assemblies.
- Less strain on tubing: The elbow turn minimises bending stress and helps extend tube life.
Extra Information
- Made for 4mm outer diameter pneumatic tubing (commonly PU/nylon). Confirm tube OD before ordering.
- Ensure the threaded port is 1/8' BSP (British Standard Pipe), not NPT.
- For best sealing, cut tubing square and clean and push fully into the fitting until it seats firmly.
- Inspect the O-ring before installation—replace if nicked, flattened, or damaged.
Pro Tip
- Hand-tighten first, then snug up gently—over-tightening can crush the O-ring or damage threads, while a clean O-ring does the sealing work.
